Abstract:

In this thesis we explore the concepts and components which can be used as individual building blocks for producing immersive virtual reality (VR) content from a single RGB-D sensor. We identify the properties of immersive VR videos and propose a system composed of a foreground/background separator, a dynamic scene re-constructor and a shape completer. We initially explore the foreground/background separator component in the context of video summarization. More specifically, we examined how to extract trajectories of moving objects from video sequences captured with a static camera. We the

Abstract:

Pairwise alignment between point clouds is an important task in building 3D maps of indoor environments with partial information. The combination of 2D local features with depth information provided by RGB-D cameras are often used to improve such alignment. However, under varying lighting or low visual texture, indoor pairwise frame registration with sparse 2D local features is not a particularly robust method. In these conditions, features are hard to detect, thus leading to misalignment between consecutive pairs of frames. The use of 3D local features can be a solution as such features come

Abstract:

Neonatal necrotizing enterocolitis (NEC) is one of the most severe digestive tract emergencies in neonates, involving bowel edema, hemorrhage, and necrosis, and can lead to serious complications including death. Since it is difficult to diagnose early, the morbidity and mortality rates are high due to severe complications in later stages of NEC and thus early detection is key to the treatment of NEC. In this thesis, a novel automatic image acquisition and analysis system combining a color and depth (RGB-D) sensor with an infrared (IR) camera is proposed for NEC diagnosis. A design for sensors

With the release of the Kinect device new possibilities appeared, allowing a simple use of image depth in image processing. The aim of this thesis is to propose a method for object detection and recognition in a depth map. Well known method Bag of Words and a descriptor based on Spin Image method are used for the object recognition. The Spin Image method is one of several existing approaches to depth map which are described in this thesis. Detection of object in picture is ensured by the sliding window technique.

Considerable effort has been devoted to finding reliable methods of correcting noisy RGB-D images captured with unreliable depth-sensing technologies. Supervised neural networks have been shown to be capable of RGB-D image correction, but require copious amounts of carefully-corrected ground-truth data to train effectively. Data collection is laborious and time-intensive, especially for large datasets, and generation of ground-truth training data tends to be subject to human error. It might be possible to train an effective method on a relatively smaller dataset using synthetically damaged dep

We investigated the advantage of combining RGB images with depth data to get more robust object classifications and detections using pre-trained deep convolutional neural networks.

We designed a resizing method called "bleeding edge" to avoid distorting the objects in the images. We present a novel method of interpolating the missing depth pixel values by comparing to similar RGB values. This method proved sup

Abstract:

碩士<br>國立交通大學<br>電子工程學系電子研究所<br>101<br>In 3D image processing, the depth estimation based on the given left and right images (the so-called stereo matching algorithms) has been widely used in many 3D applications. One type of applications tracks the body motion and/or poses with the aid of depth information. How to evaluate depth estimation algorithms for different applications becomes an issue. The conventional method of evaluating these depth estimation algorithms is often using a small number of test computer-generated images, which is insufficient to reflect the problems in the real world

Abstract:

Reconstrução de modelos 3D pode ser uma tarefa útil para várias finalidades. Alguns exemplos são a modelação de uma pessoa ou objeto para uma animação, em robótica, modelação de espaços para exploração ou, para fins clínicos, modelação de pacientes ao longo do tempo para manter um histórico do corpo do paciente. O processo de reconstrução é constituído pelas capturas do objeto a ser modelado, a conversão destas capturas para nuvens de pontos e o alinhamento de cada nuvem de pontos por forma a obter o modelo 3D.A metodologia implementada para o processo de alinhamento foi o mais genérico quanto

The system is separated into four parts, including region-of-interest (ROI) selection, feature extraction, human shape recognition and motionless human checking. First, the histogram projection, connected component labeling and moving objects segmentation are applied to select the ROIs according to the property that human is walking or standing with motion. Second, resize the ROIs based on the bilinear interpolation ap

It is important to acquire the correct orientations for indoor mapping, yet homogenous areas are hard to be detected for feature points. Therefore, taking advantage of RGB-D data, the observations contains angle and range information that construct control points to constraint the orientation modeling.

We also simultaneously utilize the depth images to efficiently analyze the 3-D space in indoor-scene images. The raw depth image from the depth camera is processed by two bilateral filters to recover a smoother and more complete depth image. On the other hand, the ICM algorithm is an unsupervised segmentation method that can preserve the boundary information well. We utilize the dense pr
